3. BRIEF INFORMATION ON FUEL - PELLETS

What are pellets?

Wood pellets are a standardised fuel. Every manufacturer must adhere to certain

conditions in order to enable ﬂawless, energy-efﬁcient heating. Pellets are made

from wooden waste, from sawmills and planning workshops, as well as from

residue from forestry operations. These “starting products” are crushed, dried,

and pressed into Pellet “Fuel” without any bonding agent.

ENplus – Pellets

This new pellets are a standard sets new benchmarks in the European pellet

market. The traceability of pellets is ensured thanks to the use of identiﬁcation

numbers. The pellet manufacturers’ production facilities and manufacturing

processes are reviewed every year. A quality assurance system ensures

the pellets comply with the requirements of the new standard and that the

conditions for trouble-free heating are guaranteed

1) in an anhydrous state

2) diameter must be speciﬁed

3) a maximum of 1% of the pellets may be longer than 40 mm,

max. length is 45 mm

4) the limit value of ≥97,7 Ma.-% applies when conducting measurements with a

lignotester (internal control)

Note

Please ask your pellet stove dealer for tested fuel and a list of monitored fuel

manufacturers.

Using poor quality or prohibited pellet fuel will have a negative effect on the

function of your pellet stove and can also lead to the warranty becoming null

and void, as well as the product liability connected with this. Observe waste

incineration legislation!

Only burn pellets that have been inspected according to ÖNORM, DIN Plus

or ENplus-A1.

Pellet storage

In order to guarantee problem free burning of the wooden pellets, it is imperative

necessary to store the fuel as dry as possible and free from impurities.

Pellets should not be kept in sacks outdoors or stored in a manner where

they are exposed to the environment. This can lead to blockages in the screw

conveyor

Note

“screw stoppers” are excluded from the warranty.

Note

Your pellet stove is only approved for the burning of wood or pellets of

tested quality. Burning straw, maize, woodchips etc. is not permitted! Non-

observance of these regulations makes void all warranty and guarantee

claims and may impair the safety of the unit!
